first exemplary embodiment
[0030]FIG. 1 is a cross sectional view illustrating a configuration of a refrigerant supply device according to a first exemplary embodiment of the present invention. The refrigerant supply device (refrigerant supply structure) 10 according to the present exemplary embodiment includes a reservoir 11 and a refrigerant liquid amount adjustment means 12.
[0031]The reservoir 11 stores refrigerant liquid caused to flow by a drive pump 21. The refrigerant liquid amount adjustment means 12 controls the flow rate of the refrigerant liquid flowing out of the reservoir 11 to a heat reception unit 22. The reservoir 11 includes a branch outlet 11c, and the branch outlet 11c is disposed in a higher position than the refrigerant liquid amount adjustment means 12. Refrigerant liquid stored in the reservoir 11 flows out of the branch outlet 11c to another reservoir 11X disposed in a lower position than the reservoir 11.
[0032]The branch outlet 11c may be connected with a branch pipe 13 for transporti...
second exemplary embodiment
[0045]Next, a second exemplary embodiment of the present invention will be described. As for the present exemplary embodiment, a phase-change cooling apparatus equipped with refrigerant supply structures 10 according to the first exemplary embodiment will be described. Hereinbelow, descriptions will be made, as an example, as to a phase-change cooling apparatus 100 equipped with refrigerant supply structures 10, which is contained in a server rack disposed in a data center (DC) or the like. In the following descriptions the “phase-change cooling apparatus 100 equipped with refrigerant supply structures 10” will be simply referred to as the “phase-change cooling apparatus 100”.
[0046]FIG. 2 is a schematic view illustrating an outline of a phase-change cooling apparatus 100 according to the present exemplary embodiment, disposed in a data center building.
[0047]The phase-change cooling apparatus 100 according to the present exemplary embodiment includes a heat reception unit module 110,...
third exemplary embodiment
[0074]Next, a third exemplary embodiment of the present invention will be described.
[0075]FIG. 9 illustrates a configuration of a heat reception unit module included in the phase-change cooling apparatus according to the present exemplary embodiment. As illustrated in FIG. 9, the heat reception unit module 110 according to the present exemplary embodiment includes valves 113 serving as refrigerant liquid amount adjustment means as well as heat reception unit liquid pipes 340 serving as pipes respectively connecting heat reception units 111 with reserve tanks 112 serving as reservoirs. The heat reception unit liquid pipes 340 are configured to include parts formed in such a way that the more downward a heat reception unit liquid pipe is located in a vertical direction, the smaller inner diameter the part of the heat reception unit liquid pipe has. More specifically, the heat reception unit liquid pipes 340 are configured to have consistently different inner diameters that depend on t...
